Hi, I have to replace some files but need to only do it once per device and have the process happen when the user launches a shortcut for an application. I do not want the process to delay the application launch due to files having to be checked every time. Also I would like a message to pop up only if the replacement of files is needed and being done to alert the user that there will be a delay while files are being updated. I hope this makes sense:) Any help is appreciated. Thanks
